Low noise:
•As of April 1, 2021, there will be new noise requirements for heating and/or cooling installations (heat pumps and air conditioners). These installations may not cause more than 40dB of noise to neighbors in residential areas.
•The SL series heat pumps are whisper quiet and meet these requirements for new and existing homes.
•The maximum sound power of these monoblock heat pumps is 53 dB(A). Measured at a distance of 1 meter, the noise level of the Maxa heat pumps is between 37.7 and 38.8 dB(A).
Technical features:
• Custom control system with microcontroller control, superheat control logic with electronic expansion valve.
• DC inverter compressors: twin-rotary DC inverter.
• Ventilation: DC inverter with axial fan
• Source exchanger: optimized circuit with finned coil, copper pipes and hydrophilic aluminum fins.
• User changer: a brazed stainless steel plate AISI 304 with reduced pressure drop on the water side.
• The refrigeration circuit is made with copper pipes and includes: condensation control, electronic expansion valve, changeover valve, high/low pressure switch, separator and liquid receiver, maintenance and control valves, double inlet pressure, high and low pressure transducers.
• Integral hydraulic system: pump with high efficiency brushless circulation pump, flow switch, air valve, pressure relief valve (6 bar), manometer, water valve for system loading / unloading
LOGIC AND OPERATION:
• All units can operate in three different modes: heating, cooling and DHW, with specific programs that improve performance in all conditions, with possible temperature curve management.
• The V5 series units are suitable for mixing valves, inverters and secondary side circulation; They can also regulate the solar thermal system, its final integration with external heat sources, and integration with external systems Home Building automation or Domotica.
•All i-32 / V5 series are remote controlled (accessory HI-T) directly accessing the system from any browser (connection to an existing network with ethernet cable).
• Standard Modbus RS485 protocol
